EDWARD J". VON PEIN, OF DA YTO N, OHIO, ASSIGNOR TO THE NATIONAL CASHREGISTER COMPANY, OF DAYTON, OHIO, A CORPORATION OF OHIO, (INCORPORATEDIN 1906.)

. .C ASH-REGISTER.

To all whom it may concern:

Be it known that I, EDWARD J. VON PEIN, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Cash-Registers, of whichI declare the following to be a full, clear, and exact description.

This invention relates to improvements in cash registers, accountingmachines, and the like and more particularly to those machines in whichindependent cash receptacles are provided for the respective clerks forkeeping their cash separate so that the responsibility of mistakes andshortages may be placed on the proper clerk and also to preventmisappropriation by one clerk of the cash in charge of another.

Cash registers having a plurality of cash drawers are usually soconstructed that access can be had to the drawer by depressing a singlekey to predetermine which drawer shall be opened at a subsequentoperation of the machine. Upon operation of the machine the selecteddrawer is released and records of one form or another are made by themachine in a record retaining device to show which drawer was opened,the nature and amount of the transaction, etc. Indicash register moneyin charge of another cators as well as different toned bells are usuallyprovided to indicate to the various clerks and the proprietor whichdrawer has been opened and enables each clerk to tell whether his draweris wrongfully opened by another clerk.

The reason for having a number of cash drawers attached to the cashregister is to give a separate receptacle for each attendant, therebyenabling the proprietor to place individual responsibility forerrors andshortages and also to prevent one attendant from fraudulentlywithdrawing from the attendant. The proprietor is able to learn whetherthe proper amount is in each attendants receptacle by comparing thecash.

in the drawer with the records made in the machine of the varioustransactions registered. It is possible, however, for one clerk to openthe cash drawer of another attendant when no one is present to detecthis wrong doing by merely pressing the other clerks key, the clerks keysusually bearing characters, such as initials, to indicate which draweris controlled by each key and which Specification of Letters Patent.

be discovered by the proprietor on comparing the cash in the drawer withthe records in'the machine.

The main object of this invention is to eliminate as far as possible theopening by one clerk or cashier of the drawer in charge of another byimproving the construction of the means controlling the opening of thedrawers. In the illustrative form shown in the accompanying drawings theobject of the invention is accomplished by providing means compellingthe operation of a plurality of special keys in combinations, the

keys being designed to control in certain combinations only the openingof the drawers. ,The drawer of each clerk is controlled by the operationof keys included in a certain corresponding combination, and as eachclerk is to know only the combination for opening his individual drawer,one clerk cannot readily open the drawer of another. A plurality ofdetent plates are provided in the particular embodiment shown, one foreach combination, and each of these detent plates can be moved only bythe operation of keys of a corresponding combination. One of the keys ineach combination is in the em.- bodiment shown. to control the extent ofmovement of a releasing means for thedrawer while the last key operatedin the' combination, which may also be the key con trolling the movementof" the releasing forms of detents for locking the operated the stud 24with the shoulder 25 on the arm 26 rocks the arm 26, shaft 16 and thearm 15 counter clockwise and in this way extension 14 on the arm 15 isdrawn out of engagement with the disk 12 to permit operation of themachine. I

The cash drawers 28 (Figs. 3 and 4) which in the embodiment are shownarranged in one vertical row are held shut by their catches 29 whichhave formed on their rear ends hooks 31 engaging drawer catch plates 32'fastened to the rear of the machine. It will readily .be seen that inorder to release anypne of the desired drawers all that is necessary isto push the end of its drawer catch 29 down so that the hook 31' willdisengage the plate 32. In the operation of the machine this is'done bythe catch trip lever 33 in the following manner. When the keys in thecombination are depressed against the tension of their springs 34 andthe register operated, a segment 35 (Fig. 1) is differentiallypositioned dependent upon which of the depressed keysis engaged by' atrip pawl 36 of the latch 37 carried by the segment. The manner in-which this is done is well known in the art and is fully explained inthe Cleal and Reinhard patent above mentioned and ref erence may be hadto this patent for a full a 39 fast to a shaft 41, to which is alsofastened a bevel gear 401 and this bevel gear 401 meshes with a bevelgear 40 (Fig. 3).

' This latter gear is splined on a shaft 42 to drawer fingers 45 (Fig.,14), one for each drawer and .these are so positioned that when thesegment 35 is stopped by a certain one of the keys in a combination, oneof the drawer fingers 45 will be under the drawer catch trip lever 33for the drawer that corresponds to the combination of keys depressed.

The finger shaft is next raised so that the finger 45 for thedrawer thatis to be opened and which has been adjusted under its drawer catch leverwill rock the appropriate lever 33 for the drawer to be selected aboutits pivot 35 forcing the opposite end of the leverdown against the endof the catch 29, and disengaging it from the plate 32. The drawer isthen ejected from the cabinet in the usual manner by a spring 46 whichcollar 54 secured to the shaft 42.

is carried on the rear wall of the drawer and is compressed against theplate 32 when the drawer is given its full inward stroke.

The finger shaft 44 can be raised by any one of a number of differentforms of lifting mechanism. In Figs. 1 and 3 of the drawings there isshown in'dotted lines a conventional device comprising a pitman and acam 51,'the cam being mounted on and near the right end of a drive shaft52. The upper end ofthe pitman has a hook which engages over the driveshaft 52 and carries at its side a roller resting on the cam 51 asshown. The enlarged lower end 47 of the pitman 50 has (Fig. 3) avertical slot 48 through which the end of a lever 56 passes. The otherend of this lever is pivoted to the frame of the machine while the leverintermediate its ends engages a The cam 51 is rigidly fastened to thedrive shaft 52 and as the shaft is turned during an operation ofthe'machine the pitman 50 will lift the lever 56 and therefore throughcollar 54 the shaft 44 against the action of the spring coiled about theshaft and compressed between the collar 54 and a flange 49 on the frame49 thereby releasing the drawer that is to be opened.

The segment gear 35 meshes also with a gear 57 loosely mounted on theshaft 11. This gear 57 meshes with a pinion wheel 58 rigidly mounted onthe side of an indi cator 59 loosely mounted on a transverse shaft 61.The indicator bears initials or numbers corresponding to the drawers toindicate which drawer has been last opened, and it is clear that whenthe segment gear 35 is differentially moved the indicator will be givena like extent of movement.

All of the mechanism mentioned so far is old in the art and needs nomore detailed description. The reason it has been covered .to suchextent is because some explanation is thought desirable to make thefollowing description of the new mechanism more easily understood.

The improvement consists of means compelling the operation of the keys 1to 9 in certain combinations to select the drawer to be opened and tounlock the machine, thus making it harder for one clerk or cashier togain access to anothers drawer. This is accomplished in the form shownby the employment of a plurality of detent plates 62 (Figs. 1, and 5 to12 inclusive) any one of which is operated by keys in a correspondingcombination only to move the plates 18 in order to unlock the machine sothat the latter may be operated. The extent of movement of thedifferential segment gear 35 when the machine is operated is determinedby one of the keys in the combination being engaged by the trip pawls 36for the latch 37 tripping the latter to allow the driver 7 5 There isone of these detents for each, combination and as there are nine keys,one for each drawer, nme comblnatlons can be employed. Five of thesecombination de-' tents are preferably arranged to the left of the plate18 on the left side of the side frame 17 and four of them are mounted tothe right of the plates 18 and on the right side of the framesupporting'the keys. They are slidably mounted on the pins 20 in thesame manner as are the plates 18, having the'slots 53 and the elongatednotches 64 through which the pins 20 pass similar to those describedabove as in the plates 18. A pin 65 on each plate 18 normally passesthrough the center of slots 66 in all the plates arranged along the sideof the respective plates 18.

The keys as usual carry pins 67, but these pins project from both sidesof the key shanks and pass over the forward edges of all of combinationdetents. When the first key in any combination, there bein two keys foreach combination in the pre erre'd form, is depressed, one of its pins67 engages an inclined edge 68 of a projection 69 on the correspondingcombination detent and raises the detentuntil the lower end of its slot66 is just in contact with the pin 65. Such movement of the detentbrings an inclined edge 70 of a projection 71, which is shown narrowerthan the projection 69, into the path of the pin of the second key inthe combination of which the key depressed is the first. Depression ofthis latter key through the engagement'of its pin 67 with the inclinededge 70 raises the combination detent one step further and as the lowerend of the slot 66 is then in engagement with the pin 65 on the plate18, the plates 18 and the combination detent are moved together duringthis last step of movement of the latter. As hereinbefore described thefinal increment of movement of the plates 18 through the engagement ofthe stud 24 with the shoulder 25 on the arm 26 rocks the shaft 16counter-clockwise to lower the locking, arm 15 out of engagement withthe disk 12 so that the machine may be operated. When the second key isdepressed the ends of the rectangular shaped projections 72 which are onthe operated detent and are normally out of the path of the pins on thekeys are moved under the pins not belonging to the combination shiftingthe moved plate, so that the keys not included in this particularcombination are locked against operation.

It is understood, of course, that the projections 69 and 71 on eachcombination, de-

shown in Fig. 1 is 37 as the 3 key and subsequently the 7 key aredepressed to operate the same. Depression of the 3 key through theengagement of the pin 67 with the inclined edge 68 of the projection 69of the 37 combination detent, raises the detent so that the lowerinclined edge 70 of the projection 71 may be brought into the path ofthe pin on the 7 key which is. the other key in the combination to bedepressed. Operation of this latter key raises the detent still furtherto raise the plates 18 and cause the latter upon the last part of theirmovement to rock the arm 26 and thereby unlock the machine. It canreadily be seen that 63 is the combination for moving the detent shownin Fig. 5, as the 6 and then the 3 key must be depressed to operate thedetent, and that 26 is the combination for operating the detent shown inFig. 6, as the 2 key and then the 6 key must be operated to actuate thedetent. vIn a like manner it is obvious that the combinations of keysfor movin the combination detents shown in Figs. 8,

9, 10, 11 and 12 are 49, 58, 95, 15, 78 and 81 respectively. If as shownin these figures the combination detents are so constructed that thenine projections 69 are adapted to be engaged respectively by differentkeys only the selected detent would be raised upon operation of thefirst key in the combination, while the second key would raise thisdetent still further and give another'detent, the inclined portion 68 ofwhose projection 69 was in the path of the pin on the second key, oneextent of movement. With the projections 64: arranged differently it isclear that the number of plates actuated would be dependent upon thearrangement of the projections 67 and the keys operated.

, In those combinations which operate thefour combination detents on theright side o f.the keys the lower key in each combinat1on determineswhich drawer shall be opened. This is true as the lowest key is thefirst to be engaged by the .trip pawl 36 to.

disconnect the latch 37 from the driving segment 75, the operation ofthe segment and the latch being fully described in the aforesaid LettersPatent granted to J. P. Cleal and .F. A. Reinhard. As the lower keydetermines the extent of movement of the segment gear 35 in operationsin which the 'ma the left side of .the

These mem-' from operating the latch.To this end the five combination detents on side frame 17, which are thecombination detents controlling" the unlocking of the machine when oneof the drawers corresponding to the five upper positions of the-segmentis to be opened, are provided with V-.shaped members 76 as bers arepivoted on pins 77 to these combination detents and each is sopositioned on its supporting detent that the end of the forward arm.78of the V-shaped member is in the path of the lower key in the corresponding combination so that depression of this key rocks the member aboutits pivotal centerand the inclined edge SOpf the reararm 79 of themember is thereby held while the key is retained depressed the path ofthe trip pawl 36, the upper end .of the trip pawl being provided with ahorizontally extending 7 arm 79 of the member opening of the drawer,

flange 85 which extends of the combination detents carrying thesemembers'78. When the segment gear 35 is actuated, the trip pawl 36engages only the rocked by the depressed key but the arm 79 deflects thetrip pawl 36 from its normal course about the end of the key operatingthe V-shaped memher and without being obstructed by the lower end of thedepressed key-"as the trip pawl is allowed to be pressed rearward aboutits pivot 84 against the action of its.

spring 81. As the trip pawl 36 passes out of engagement with the arm 79and around the lowermost depressed key its .spring 8 1 pushes it forwardto normal position so'that' it will engage the end of the key andthereby trip the latch 37. Leaf springs 82 project from the members 78between their arms their combination detents and serve to restore themembers to initial position after the depressed combination keys arereturned outward to normal position upon being re leased and to normallyhold'the members out of the path of the arms 79 as shown.

With the fingers 45 helically arranged on 44 as is usual in the art theythe finger shaft drawer to be opened is in the same relative position inthe limiting the extent of movement of the seg-' ment gear 35 andthereby controlling the the fingers 45 so arranged that one key ofprevent the lower keys in the across the rear edges upper depressed,

tier of drawers that the key not in the same every combination isreadily ascertained by all of. the clerks, a clerk could press the knownkey of another clerks combination, which bears the same relation to theother keys as does the drawer opened by such clerk to the other drawers,and then by depressing the other keys until the other key of thecombination is found, open the drawer assigned to the other clerk. Toeliminate as far as practical the possibility of one clerkascertaininganother combination and opening the drawer of such otherclerk the fingers 45 in the preferred form shown have been staggered onthe finger shaft so that the drawer to be opened is relative position inthe row of drawers that its controlling key in the combination is in thebank.

For exam le in the preferred form, the finger 45 Fig. 14) is the fourthfinger from the top of the shaft and is for opening the fourth drawerfrom the top, and its sitions in is inthebank. With sired so thafi therelationship with angular position is 252 from the position in which itwill engage, when lifted, the drawer catch trip lever 33 for the fourthdrawer. As one'step of movement ofthe segment gear 35 rotates thefingershaft 36 it is evident that the segment gear 35 moves 'f'seven stepsbefore the finger 45 which is 252 from operating position is inoperative its respective drawer catch trip lever 33, and therefore asthe key stops movement of the segment gear 35 at' the end of its seventhstep of movement, the combination'37 (Fig. 1) controls the opening ofthe fourth drawer in thevtier. The finger 45 is the seventh finger fromthe top of the shaft 44 and is for unlocking the seventh drawer and is144 from the position in which it will engage, when raised,the drawercatch trip lever 33 for the seventh drawer and therefore the combination63 (Fig. 5) controls the opening of the seventh drawer. In a like'mannerthe finger45 is the third from the top of shaft 44 and eight steps ofmovement, the is the fifth from the top of shaft 6 steps of movement,and the is the sixth from the top of shaft 5 steps of movement fromtheir powhich they when raised will engage their respective trip levers33 and the combinations 26, 49 and 58 (Figs. 6, 7 and 8 respectively)control the opening of third, fifth and sixth drawers respectively. The

10, and 112 respectively) which efiect the positioning of fingers 45 4545 and 45 respectively eighth, second, first and ninth from the top'ofshaft 44, control in a similar manner'the opening of the eighth, second,first and ninth drawers respectively. Of course it is obvious that thearrangement of these fingers 45 can be varied as decombinations showncan ated positions is shown in Fig. 13 and this.

initial of the clerk to whom the drawer is assigned.

The means for locking the keys in opermeans will now be described. Ninelocking dogs '90 are pivotally mounted by pins 89 on aplate 91. Theplate 91 is slidably mountedat the left of the last combination detentto the left of the keys, on the pins 20 which pass into the slots 92 inthe plate. The locking dogs 90 are bell crank in form and their forwardarms form hooks and have inclined faces 93 normally in the projectingThe other arms ofv the dogs are provided with flanges 94 which arenormally in engagement with the rear edge of the plate 91 and so held inpath of the end of the pins 67 "that position by also being inengagement with the periphery of a segment plate 95.

so that'the upper wall of the recess 104 be '45 low the inclined face 93will engage over:

a clined Atits rear end the segment plate 95 is bifurcated and straddlesthe transverse shaft 96 and near its periphery carries apin 97 passinginto a slot 98 formed in a pro ection 99 of the plate 91. A spring 100which is under tension between a pin 101 on a projection 99 and a pin102 on the plate 95 tends to pull the plate 95 forward to keep thelocking dogs in normal position. When a key is depressed its pin -67engages the inclined face 93 of its locking dog and rocks the lattercounter-clockwise, as viewed in Fig. 13, and as the pin passes oif theinface the plate 95, through the spring 100, restores the detent tonormal position the pin 67 on the key to retain the key in c depressedposition. In'this manner it will be seen that as each key is depressedits corresponding locking dog will'lock it in depressed position withoutoperating the other dogs so that two keys can be operated in the bankduring the same operation of the machine.

Near the end of the operation of the machine the-shaft 96 is rockedupward past thenormal position (shown; in Fig. 13) as described in theabove mentioned Cleal and Reinhard patent and an arm 105 fast to theshaft is thereby brought into engagement with an anti-friction roller106 mounted on the segment plate 95 to rock the plates 95 and 91 as aunit, they being connected, as described by the pin 97 on the plate 95.As the locking dogs 90 are held by the plate 95 from moving relativelyto the plate 91 upon movea 1 V f 1,284,238;

ment of the plates 91 and 95 it can readily be seen that the recesses104 of the dogs in locking'relationship with the keys will be carriedout of engagement with the pins on the depressed keys so as to permitthe springs 34 coiled about the key shanks to force the keys outward totheir normal position. After the keys are released the plates .95 and 91are returned by a spring 111 attached at one end to the frame and at theother to the plate 95, to lower and normal positions.

The plate 91and' also, through the pin 97, the plate 95 may be movedupward to re lease any key depressed in error before the actuation ofthe operating mechanism by rocking a shaft 108 carrying an arm 109clockwise as the lower end of the plate is in engagement with this arm.The shaft 108 is connected with a special manipulative arm or device butasthis key releasing mechanism is old in the art it need notbe describedin detail herein. H

So far as applicant is aware there has been prior to this no drawerreleasing mechanism controlled by manipulative means operable' only incombinations and it is intended that the claims included herein shouldcover all the various forms of'embodiment of which the rinvention issuscep- 95 tible. It is apparent that any particular number of drawersis not essential to the successful operation of the improvement and alsothat any number of combination keys may be employed as desired.

While the form of mechanism herein shown and described is admirablyadapted to fulfil the objects primarily stated, it is to be understoodthat it is not intended to confine the invention to the oneform of 105embodiment shown and described herein, as it is susceptible ofembodiment in various forms, all coming within the scope of the a claimswhich follow.
